Is the declining acreage of land used for farming in the United States a major problem?

a. No, food is essential for life and therefore there is no higher valued use for land than providing foodstuff; eventually government regulators will step in an reverse the current trend.

b. No, it is primarily a reflection of the increased productivity in agriculture and shift of the land to higher valued uses.

c. Yes, unless government regulation slows the commercial development of land, market forces will lead to the virtual depletion of land for agricultural use.

d. Yes, unless public pressure leads to a reversal of this trend, America can expect food shortages in the future.
